Question

"What is the output of this code?
arr = [5, [9, 4, 6], [8]]
puts arr[1][0]"

how do u get the out put 5?
I tried running- assuming 5 is contained in location 0 in the 0 arr.
puts arr[0][0]
but once running it , result came back as 1

Answer 1

You'll use the square bracket notation only when you want to acess an array element. In this case, 5 is an integer. 😉

For example:
arr[0] = 5
arr[1] = [9, 4, 6]
arr[1][1] = 4
...

Answer 2

Result: 9
